My micrometer dimensions of the bores are as follows in order from front to back, not firing order:
#1 3.8080
#2 3.8070
#3 3.8065
#4 3.8070
#5 3.8065
#6 3.8065
I checked them each three times at the top of the cylinder with zero ridge after a light hone.
The bottom of the cylinders are less than .006 difference on all bores.
Pistons all measured 3.8035 with no material differences.
I remember thinking .005 max difference was fine for a hone and re-ring and I appear to be within that window.
Are those numbers ok or do we need to knurl the pistons?
We are at .060 on bore now and dont want to bore any further.
